CAR-COUPLING.

SPECIFICATION forming part of Law's Patent No. 455,141, dated J'une30,1891.

v Application filed April 2, 1891. Serial No. 387,433. (No model.)

To ctZZ whom, it 17mg concern:

Be it known that I, SEIBERL Wool) WORTH, a citizen of the United Statesof America, residing at Ellinwood, in the county of Barton and State ofKansas, have invented certain new and useful Improvements inCar-Couplings; and I do hereby declare the following to be full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and to letters ofreference marked thereon,which form a part of this specification.

This invention relates to improvements in automatic car-couplings ofthat class technically known as hook and pin.

The object of the invention is to provide a coupling by means of whichcars may be antomatically connected and readily disconnected, the partsbeing constructed so that the ordinary link-and-pin coupling can be usedin connection therewith; and it consists in the construction andcombination of the parts, as will be hereinafter fully set forth, andparticularly pointed out in the claims.

In the accompanying drawings, forming part of this specification, Figure1 is a perspective View. Fig. 2 is a plan view partly in section. Fig. 3is a detail View of one of the pins detached.

A refers to the draw-bar of the coupling, which is attached to the carinthe usual manner, the front end being recessed, within which an ordinarylink may be placed when the de- 1vice is used as an ordinarylink-and-pincoup- To the forward end of the draw-bar A are rigidly attached, eitherby bolts or by being integrally formed therewith, cross-pieces B B.Between the pieces are placed blocks 12, which form recesses, as shown.In one of these recesses is loosely pivoted a hook O, which is locatedto permit a horizontal swinging movement upon its pivot (Z. This hook isprovided with a rounded outer edge and a recess 0, havg astraight frontwall, which is adapted to engage with a pin secured in the oppositedraw-head, this pin lying in peculiar openings formed in thecross-pieces B B adjacent to the draw-bar. The hooks C have shoulders c,which abut against the blocks 1) to limit the outward movement of saidhooks, while excessive inward movement is prevented by the inner edgeabutting against the draw-bar or the rear outer edge against the blockb.

To near the outer ends of the cross-pieces B B, beyond the apertures orperforations e,

are vertical pins f f, placed'on a line with each other, which areadapted to engage with the bent portions of'the spring F, said springbeing adapted to engage with the outer edges of the hooks and throw thesame into engagement with the pins E. The spring F has its forward endbent back upon itself to pass around both of the pins, while the frontfree end may abut against one of the blocks 19. The coupling-pins E havetwo straight faces and a third on the segment of a circle, so as toprovide a rounded portion against which the hooks will abut to ride overthe same and engage with the straight face. By provid ng a pin of thisconstruction the notched portion of the hook will be located adjacent tothe draw-bar A, and as near the center thereof as practical whenprovision is made for the ordinary link and pin. It will be obvious thatwhen the draw-heads come together, the pins being properly placedtherein, the cars will be automatically coupled. To uncouple the cars,

it will be necessary to remove the pins. The

springs hold the hooks constantly in engagement with the vertical pinsand permit the draw-heads to have a slight lateral movement.

Having thus described my invention, I claim as new and desire to securePatent-- 1. In a car-coupling, the combination of a pair of draw-headsconstructed substantially as shown and provided withhorizontally-movable hooks, pins E, having straight and rounded faces,springs F, carried by the drawheads and adapted to bear uponthehorizontally-movable hooks for holding the same in engagement withone of the angular faces of the coupling-pins, substantially as setforth.

2. In combination with a draw-head constructed substantially as shownand provided with laterally-extended portions, within one of which ahook is pivoted, a spring F, secured to the opposite extended portionand provided with an end which is bent upon itself to proby Letters videforwardly and rearwardly extending members, said spring being held inplace by vertical pins f f, substantially as set forth.

The combination, in a car-coupling, of the draw-heads constructedsubstantially as shown and provided with horizontally-swinging hooks O,springs carried by the opposite end of the draw-head, said draW-headhaving an aperture with one rounded edge and two straight edges toreceive pin E, said pin hav ing straight edges and a rounded edge,substantially as set forth.

4. A coupling-pin for hook-anthcatch car couplings, having two straightfaces at right angles with each other and athird face on the segment ofa circle, in combination with the coupling-hooks which are adapted toride over the curved or rounded portion of the couplingpin and engagewith one of the straight faces thereof, substantially as set forth.

In testimony whereof I a'llix my signature in presence of two witnesses.
